Find an equation of a parabola with a vertex at the origin of directrix y = -2.5

Step-by-step explanation:

Since the directrix is , it means the axis of the parabola is parallel to the y-axis.

Also, the vertex is at the origin so the parabola opens upwards.

The equation of a parabola with these properties is of the form , where ,that is the distance between the vertex and the directrix.

.

Since the parabola opens upwards, we choose .

The equation of the parabola now becomes,

Or

See graph

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
